     43  * A feature can be anything.  But most of them share certain characteristics.
     44  *
     45  * When a feature defines vtxfmt entries, they can be initialized and
     46  * installed by
     47  *   _MESA_INIT_<FEATURE>_VTXFMT
     48  *   _mesa_install_<feature>_vtxfmt
     49  *
     50  * When a feature defines dispatch entries, they are initialized by
     51  *   _mesa_init_<feature>_dispatch
     52  *
     53  * When a feature has states, they are initialized and freed by
     54  *   _mesa_init_<feature>
     55  *   _mesa_free_<feature>_data
     56  *
     57  * Except for states, the others compile to no-op when a feature is disabled.
     58  *
     59  * The GLAPIENTRYs and helper functions defined by a feature should also
     60  * compile to no-op when it is disabled.  But to save typings and to catch
     61  * bugs, some of them may be unavailable, or compile to ASSERT_NO_FEATURE()
     62  * when the feature is disabled.
     63  *
     64  * A feature following the conventions may be used without knowing if it is
     65  * enabled or not.
